Description

CROSS REFERENCE TO RELATED APPLICATIONS

This application is based upon and claims the benefits of priorities from Japanese Patent Application No. 2006-245127 filed on Sep. 11, 2006, the entire contents of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present invention relates to a slot machine having symbols rearranged on a display and a method of playing a game with the slot machine.

RELATED ART

In a conventional slot machine, a predetermined number of symbols are rearranged on a display thereof such that a winning combination formed in the rearranged symbols is provided (e.g., U.S. Pat. No. 6,960,133).
In particular, in the case of a scatter symbol, a payout rate corresponding to the winning combination is determined by the number, which is greater than a predetermined number, of scatter symbols in the rearranged symbols displayed on the display. Therefore, it is not necessary that the scatter symbols are aligned on a pay line, but the number of scatter symbols are rearranged on the display in order to obtain the winning combination. However, it may be required that the scatter symbols are aligned and appear from the left or right reel in a series with some slot machine.
That is, the rearrangement of symbols is directly related to the winning combination. Therefore, if a new and innovative relationship between the way of displaying symbols and the payout is created with a hardware with which rearrangement of the symbols is realized, the impression given to the player may be enormous such that it is possible to generate a new entertainment feature with the slot machine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

In the following, embodiments according to the present invention are described with reference to the drawings.
FIG. 1 is a diagram showing features of a slot machine as an embodiment of the present invention. The stage number being counted from the top stage and the right or left position are utilized to specify one of the images displayed in a chronological order on a lower image display panel 6 shown in FIG. 1. The way of illustrating the features is the same as in FIG. 14 to be described later. In the slot machine according to this embodiment of the present embodiment, a symbol display frame 102 comprising: symbol display areas of 6 rows by 6 columns is displayed on the lower image display panel 6 as shown at the left position on the 1st stage in FIG. 1. Further, a BET number display part 101, a credit number display part 8, and a payout number display part 9 are displayed on the lower image display panel 6.
When a unit game is started with a BET number displayed on the BET number display part 101, one symbol is fixedly displayed on each of the symbol display areas of 3 rows by 6 columns which form a predetermined range positioned at the bottom edge 102B of the symbol display frame 102 as indicated in the lower image display panel 6 shown at the right position on the 1st stage in FIG. 1.
One symbol is displayed in each of the symbol display areas of 1 row by 6 columns being positioned at the top edge 102A of the symbol display frame 102 as indicated in the lower image display panel 6 shown at the right position on the 2nd stage in FIG. 1. Then, six symbols aligned in the 1 row by 6 columns are displayed as they are dropping (moving downward) in the symbol display frame 102.
When each symbol having been displayed as being moved downward is eventually displayed as being landed on the predetermined range of symbol display areas of 3 rows by 6 columns in which the symbols are displayed statically as displayed in the lower image display panel 6 shown at the left position on the 2nd stage in FIG. 1. Each dropping symbol is displayed statically in each symbol display area.
Each symbol is displayed in any one of three colors within the symbol display frame 102. The display color of a symbol indicates an attribute of the symbol itself. In this regard, in FIGS. 1 and 14, the kind of pattern filling each symbol stands for the display color (attribute) of each symbol so as to distinguish the display color (attribute) of the symbol.
When the symbols displayed statically in the symbol display areas have the same display color (attribute) as the symbol display areas of the symbols neighbor with each other on at least one of the four directions: up and down and left and right, the symbols displayed in the symbol display areas neighboring with each other are displayed and treated in a connected manner. In this regard, the symbols in a connected state are connectedly displayed by applying texture mapping to backgrounds thereof in the symbol display areas in which the symbols are displayed, as indicated in the lower image display panel 6 shown at the left position on the 2nd stage in FIG. 1.
When four or more symbols are displayed in the corresponding number of symbol display areas neighboring with each other on one of the four directions in the connected manner, an outer frame 106 of a group of the corresponding number of symbol display areas in which the symbols having the same display color (attribute) are displayed is highlighted as indicated in the lower image display panel 6 shown at the left position on the 2nd stage in FIG. 1. Then, an elimination display is performed by removing highlight of the outer frame 106 and each symbol in the outer frame 106 as indicated in the lower image display panel 6 shown from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 1. At this time, a payout corresponding to the elimination display is provided. In this regard, the amount of the provided payout is equal to an amount obtained by multiplying the number of outer frames 106 subjected to the elimination display by a standard amount of payout. More specifically, there are two outer frames 106 subjected to the elimination display on the lower image display panel 6 shown from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 1. Since the standard amount of payout is set to “10” at this moment, a payout amounting to 2×“10”=“20” is provided such that “20” of the amount of payout is displayed in the payout number display part 9 as a payout number. When the payout is provided, the standard amount of payout is doubled.
Subsequently, if there are symbols displayed statically in the symbol display areas located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102, the symbols are displayed as they are moved downward (dropping) within the symbol display frame 102 as indicated in the lower image display panel 6 shown from the left position on the 3rd stage to the right position on the 3rd stage in FIG. 1.
The game further progresses in a similar manner as described in the above-mentioned case. That is, when each symbol is displayed as being moved downward and then as being landed on a range of a symbol display area in which a symbol is displayed statically as indicated in the lower image display panel 6 shown on the right position on the 3rd stage in FIG. 1, each landed symbol is displayed statically in the symbol display area. However, here, even when each symbol is displayed as being moved downward and as being landing on the lower edge 102B of the symbol display frame 102, each symbol is displayed statically in the symbol display area.
When the symbols displayed statically in the symbol display areas have the same display color (attribute) and the symbol display areas are neighboring with each other on at least one of the four directions: up and down and left and right, all the symbols displayed in the symbol display areas neighboring with each other are treated as being in a connected state. The symbols in the connected state are connectedly displayed by applying the texture mapping to backgrounds of the symbol display areas in which the symbols are displayed, as indicated on the lower image display panel 6 shown on the right position on the 3rd stage in FIG. 1.
When four or more symbols are displayed in the corresponding number of symbol display areas neighboring with each other on one of the four directions in the connected manner, an outer frame 106 of a group of the corresponding number of symbol display areas in which the symbols having the same display color (attribute) are displayed is highlighted as indicated in the lower image display panel 6 shown at the right position on the 3rd stage in FIG. 1. Then, an elimination display is performed by removing highlight of the outer frame 106 and each symbol in the outer frame 106 as indicated in the lower image display panel 6 shown from the right position on the 3rd stage to the right position on the 4th stage in FIG. 1. At this time, a payout corresponding to the elimination display is provided. In this regard, the amount of the provided payout is equal to an amount obtained by multiplying the number of outer frames 106 subjected to the elimination display by the standard amount of payout. More specifically, there is one outer frame 106 subjected to the elimination display on the lower image display panel 6 shown from the right position on the 3rd stage to the right position on the 4th stage in FIG. 1. Since the standard amount of payout is “20” at this moment, a payout amounting to 1×“20”=“20” is provided such that a numeral (“40”) obtained by adding “20” of the amount of payout to the current payout number is displayed in the payout number display part 9 as the payout number. When the payout is provided, the standard amount of payout is further doubled.
Also subsequently, if there are symbols displayed statically in the symbol display areas located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102, the symbols are displayed as they are moved downward (dropping) within the symbol display frame 102. The game further progresses in a similar manner as described in the above-mentioned case.
If there are no symbols displayed in the symbol display areas located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102 as indicated in the lower image display panel 6 shown at the left position on the 4th stage in FIG. 1, the unit game terminates at the time.
The number of rows of symbols (that is, the number of symbols) to be displayed as dropping from the top edge 102A of the symbol display frame 102 at the time of the start of the unit game may be changed based on a BET number having been bet for this unit game. In the example shown in FIG. 1, when the BET number is “1”, six symbols aligned in 1 row by 6 columns are displayed as dropping from the top edge 102A of the symbol display frame 102. In this regard, in the present embodiment, when the BET number is “1”, six symbols aligned in 1 row by 6 columns are displayed as dropping from the top edge 102A of the symbol display frame 102. When the BET number is “2”, twelve symbols aligned in 2 rows by 6 columns are displayed as dropping from the top edge 102A of the symbol display frame 102. And when the BET number is “3”, eighteen symbols aligned in 3 rows by 6 columns are displayed as dropping from the top edge 102A of the symbol display frame 102.

The coin counter 21C is provided in the inside of the coin receiving opening 21, and checks the suitability of a coin inserted into the coin receiving opening 21 by the player. The coin counter 21C discharges objects other than the authentic coin from the coin payout opening 23, and outputs an input signal to the game controller 100 when detecting the authentic coin.
The reverter 21S operates based on a control signal output from the game controller 100, and distributes coins recognized as the authentic coins by the coin counter 21C to a cashbox (not illustrated) or the hopper 66 installed in the slot machine 1. The cold cathode tube (CRT) 81 is installed in the rear side of the lower image display panel 6 and the upper image display panel 7, lit based on a control signal from the game controller 100, and functions as backlight.
Next, a main control program executed in the slot machine 1 related to the present embodiment is described in detail with reference to the drawings. FIG. 10 shows a flowchart of the main control program.
In the slot machine 1, the memory card 53 is assumed to be already inserted into the card slot 53S of the gaming board 50, and the GAL 54 is assumed to be attached to the IC socket 54S.
First, when an electric power switch is turned on in the power supply unit 45 (application of power), a game controller 100 is activated to execute authentication read process of step (hereinafter abbreviated as S) 1. In the authentication read process, the mother board 40 and the gaming board 50 which form the game controller 100 execute separate processing in parallel.
That is, in the gaming board 50, the CPU 51 reads the preliminary authentication program stored in the boot ROM 52, and executes preliminary authentication of confirming and proving that the authentication program is not altered in advance before loading into the mother board 40 in accordance with the read preliminary authentication program.
On the other hand, in the mother board 40, the main CPU 41 executes the BIOS stored in the ROM 42, and decompresses compressed data built in the BIOS into the RAM 43 to execute a BIOS decompressed into the RAM 43, and diagnoses and initializes various peripheral devices.
Subsequently, the game controller 100 reads an authentication program stored in the ROM 55 to perform authentication of confirming and proving that the game program stored in the memory card 53 inserted in the card slot 53S is not altered. After the authentication process terminates normally, the game controller 100 writes the game program and the like subjected to the authentication (authenticated) in the RAM 43, and acquires the payout rate setting data and the country identification information.
After performing the above-mentioned process, the game controller 100 finishes the authentication read processing.
In S2, the game controller 100 sequentially reads and executes the game program and the like authenticated in the authentication read process of S1 from the RAM 43 to execute the main game process. When the main game process is executed, the game in the slot machine 1 according to the present embodiment is played. Then, the main game process is repeatedly executed while the electric power is supplied to the slot machine 1.
Next, the sub-process of the main game process in S2 is described based on FIG. 11. FIG. 11 is a flowchart of the main game process program in the slot machine 1 according to the present embodiment. Each program shown in the flowchart of FIG. 11 is stored in the ROM 42 or the RAM 43 provided in the slot machine 1, and executed by the game controller 100.
First, in S11 as shown in FIG. 11, the game controller 100 performs a predetermined initial setting, and then executes start acceptance process of setting the insertion of coins, the BET number, and the like. At this time, in the start acceptance process, the player performs the insertion of coins and a bet operation using the 1-BET button 16 and the MAX-BET button 17.
Next, in S12, the game controller 100 determines whether or not the spin button 13 is pressed. Whether or not the spin button 13 is pressed is determined based on whether or not an input signal is received from the spin switch 13S.
When the spin button 13 is not pressed (S12: NO), the game controller 100 returns to the start acceptance process (S11) again. The operation of the correction of the BET number and the like is enabled at this time. On the other hand, when the spin button 13 is pressed (S12: YES), the BET number set based on the operation of the 1-BET button 16 and the MAX-BET button 17 is subtracted from the credit number owned by the player, and the resultant data is stored in the RAM 43 as BET information.
Further, the game controller 100 displays the BET number and the credit number in the BET information in the BET number display part 101 and the credit number display part 8 by transmitting a control signal to the graphic board 68.
On and after S13, the game controller 100 executes the unit game process.
First, in S13, the game controller 100 executes a game lottery process.
The sub-process of the game lottery process in S13 is described based on FIG. 12. FIG. 12 is a flowchart of a game lottery process program in the slot machine 1 according to the present embodiment. Each program shown in the flowchart of FIG. 12 is stored in the ROM 42 or the RAM 43 provided in the slot machine 1, and executed by the game controller 100.
First, in S21 as shown in FIG. 12, the game controller 100 executes a lottery process for a first static display. In the lottery process, the display color (attribute) of each symbol displayed statically in each symbol display area within the prescribed area 104 at the time of starting the unit game is determined.
Specifically, a plurality of color patterns in which the display color (attribute) of each symbol displayed statically in each symbol display area within the prescribed area 104 is set in advance are read from the game program. On the other hand, one random number value is selected from a numeric value range of “0 to 255” by executing a random number generation program included in the lottery program stored in the RAM 43. Then, a color pattern is determined with reference to the symbol weighting data corresponding to the payout rate setting data and based on the selected random number value. Then, after storing the determined color pattern in the RAM 43, the process shifts to S22.
Next, in S22, the game controller 100 executes a lottery process for a first drop display. In the lottery process, the display color (attribute) of each symbol to be displayed as dropping from the top edge 102A of the symbol display frame 102 at the time of starting the unit game is determined according to the BET number.
Specifically, a plurality of color patterns in which the display color (attribute) of each symbol to be displayed as dropping from the top edge 102A of the symbol display frame 102 at the time of starting the unit game is set in advance are read from the game program. Then, a range of color patterns which can be determined in S22 from the plurality of color patterns is limited based on the BET information stored in the RAM 43 in S12. For example, when the BET number set for the unit game is “1”, the range is limited to a color pattern corresponding to the group 105A (refer to FIG. 6) having six symbols aligned in 1 row by 6 columns. When the BET number set for the unit game is “2”, the range is limited to a color pattern corresponding to the group 105B (refer to FIG. 7) having twelve symbols aligned in 2 rows by 6 columns. When the BET number set for the unit game is “3”, the range is limited to a color scheme pattern corresponding to the group 105C (refer to FIG. 8) having eighteen symbols aligned in 3 rows by 6 columns. On the other hand, one random number value is selected from a numeric value range of “0 to 255” by executing the random number generation program included in the lottery program stored in the RAM 43. Then, a color pattern is determined from the color patterns which are in the limited range with reference to the symbol weighting data corresponding to the payout rate setting data and based on the selected one random number value.
Then, after storing the determined color pattern in the RAM 43, the game controller 100 returns to the main game process of FIG. 11.
Next, returning to the main game processing of FIG. 11 and proceeding to S14, the game controller 100 executes symbol display control processing.
The sub-process of the symbol display control process in S14 is described based on FIG. 13. FIG. 13 is a flowchart of a symbol display control process program in the slot machine 1 according to the present embodiment. Each program shown in the flowchart of FIG. 13 is stored in the ROM 42 or the RAM 43 provided in the slot machine 1, and executed by the game controller 100.
First, as shown in FIG. 13, the game controller 100 performs a first static display process in S31. This process is processing of displaying statically one symbol, in the color pattern determined in the lottery process for the first static display (S21), in each of the eighteen symbol display areas 103 of 3 rows by 6 columns which form the prescribed area 104 within the symbol display frame 102 in the lower image display panel 6 (for example, refer to the right position on the 1st stage in FIG. 1). This process is processing performed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 stores the arrangement situation of symbols within the symbol display frame 102 (The display color (attribute) of each symbol is also included. The same applies in the following) in the RAM 43 as arrangement information.
Then, in S32, the game controller 100 executes a first drop display process. This process is processing of performing the drop display of a plurality of symbols aligned in the color pattern determined in the lottery process for the first drop display (S22) by moving the plurality of symbols within the symbol display frame 102 downward from the top edge 102A of the symbol display frame 102 in the lower image display panel 6 (for example, refer to FIG. 1 from the right position on the 2nd stage to the left position on the 2nd stage). This process is processing executed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 updates the arrangement information stored in the RAM 43 based on the arrangement situation of the symbols within the symbol display frame 102.
Then, in S33, the game controller 100 executes a second static display process. This process is processing of, when the symbols during the drop display are displayed within the symbol display frame 102 of the lower image display panel 6 as the dropping symbols are landing on a range of a symbol display area in which a symbol is displayed statically or on the bottom edge 102B of the symbol display frame 102, and the symbols are displayed statically in the respective symbol display areas (for example, refer to the left position on the 2nd stage in FIG. 1, the right position on the 3rd stage in FIG. 1, or the left position on the 4th stage in FIG. 1). This process is processing executed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 updates the arrangement information stored in the RAM 43 based on the arrangement situation of the symbols within the symbol display frame 102.
In S34, the game controller 100 determines whether or not the symbols statically displayed after the landing display are adjacent to symbols having the same attribute (display color) as the attribute (display color) of the symbols concerned in any one of the four directions vertically and horizontally within the symbol display frame 102 of the lower image display panel 6. The determination is made based on the arrangement information in the RAM 43 updated in S33. Here, when it is determined that the symbols statically displayed after the landing display are not adjacent to the symbols having the same attribute (display color) as the attribute (display color) of the symbols concerned (S34: NO), the game controller 100 proceeds to S36 to be described later. On the other hand, when it is determined that the symbols statically displayed after the landing display are adjacent to the symbols having the same attribute (display color) as the attribute (display color) of the symbols concerned (S34: YES), the game controller 100 proceeds to S35.
In S35, the game controller 100 executes connection display process. This process is processing of applying the texture mapping to a background in the symbol display area in which each symbol determined in S34 to be adjacent to a symbol of the same attribute within the symbol display frame 102 of the lower image display panel 6 is displayed (for example, refer to the left position on the 2nd stage in FIG. 1, or the right position on the 3rd stage in FIG. 1). This process is processing executed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 adds, to the arrangement information stored in the RAM 43, connection information which indicates that each symbol determined to be adjacent to a symbol of the same attribute in S34 is treated as being in a connected state.
In S36, the game controller 100 determines whether or not four or more symbols having the same attribute (display color) are displayed in symbol display areas neighboring with each other within the symbol display frame 102 of the lower image display panel 6. The determination is made based on the connection information added to the arrangement information in the RAM 43 in S35, and the like. Here, when it is determined that four or more symbols having the same attribute (display color) are not in respective symbol display areas neighboring with each other (S36: NO), the game controller 100 returns to the main game process in FIG. 11. On the other hand, when it is determined that four or more symbols having the same attribute (display color) are in respective symbol display areas neighboring with each other (S36: YES), the game controller 100 proceeds to S37.
In S37, the game controller 100 executes an elimination display process. First in this process, the outer frame 106 of a group formed by the symbol display areas in which the four or more symbols of the same attribute are determined in S36 to neighbor to each other are displayed is highlighted within the symbol display frame 102 of the lower image display panel 6 (for example, refer to the left position on the 2nd stage in FIG. 1, or the right position on the 3rd stage in FIG. 1). Further, in this process, the elimination display is performed within the symbol display frame 102 of the lower image display panel 6 after the highlighting, wherein the display of each symbol of the four or more symbols determined in S36 to neighbor to each other is removed along with the outer frame 106 (for example, refer to from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 1, or from the right side of the 3rd stage to the right side of the 4th stage in FIG. 1). This process is processing executed between the game controller 100 and the graphic board 68.
In this process, the game controller 100 updates the arrangement information stored in the RAM 43 based on the arrangement situation of the symbols within the symbol display frame 102.
In S38, the game controller 100 executes an awarded payout display process. This process is processing of adding an amount obtained by multiplying the number of outer frames 106 removed in S39 by the standard amount of payout to the current payout number, and displaying a numeral after the addition on the payout number display part 9 (for example, refer to from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 1, or from the right position on the 3rd stage to the right position on the 4th stage in FIG. 1). This process is processing executed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 stores the numeral displayed in the payout number display part 9 in the RAM 43 as payout information or updates the RAM 43.
Then, in S39, game controller 100 executes a standard payout double-up process. This process is processing of doubling up the standard amount of payout used in S38. Further, in this process, the game controller 100 updates the standard amount of payout stored in the RAM 43 to the standard amount of payout doubled here.
The standard amount of payout at the time of the unit game start is initialized to “10” in S12.
In S40, the game controller 100 executes a second drop display process. In this process, when there are symbols statically displayed in the symbol display areas located above the symbol display areas in which the elimination display of symbols is performed in S37, the drop display is performed by moving the symbols downward within the symbol display frame 102 of the lower image display panel 6 (for example, refer to from the left position on the 3rd stage to the right position on the 3rd stage in FIG. 1, or from the right position on the 4th stage to the left position on the 4th stage in FIG. 1). At this time, when the game controller 100 recognizes that there are symbols to be treated as being in a connected state among the symbols subjected to the drop display according to the connection information added to the arrangement information in the RAM 43, the game controller 100 performs the drop display of each symbol being in the connected state by integrally moving each symbol downward. This process is processing executed between the game controller 100 and the graphic board 68.
Further, in this process, the game controller 100 updates the arrangement information stored in the RAM 43 based on the arrangement situation of the symbols within the symbol display frame 102.
Subsequently, the game controller 100 returns to S33 and repeats each process on and after S33. Then, proceeding to S36, when the game controller 100 determines that four or more symbols having the same attribute (display color) are not in the state of neighboring with each other (S36: NO), the game controller 100 returns to the main game process in FIG. 11.
Returning to the main game process in FIG. 11, the game controller 100 executes the payout process in S15. In this payout process, the payout amount obtained in the unit game (amount which is the numeral displayed in the payout number display part 9, and shown in the numeral of the payout information stored or updated in the RAM 43) is paid out to the player. At this time, the game controller 100 causes the credit number display part 8 to add the numeral displayed in the payout number display part 9 and display the sum by transmitting a control signal to the graphic board 68, while causing the payout number display part 9 to display “0”.
Further, in this payout process, it is also possible to pay out coins corresponding to the credit number (one credit corresponds to one coin) by pressing the CASHOUT button 15, and it is also possible to pay out the bar-coded ticket 25.
Subsequently, the main game process is executed again.
In addition, the present invention is not limited to the above embodiment, and various modifications may be made in the range without departing from the scope of the present invention.
For example, as shown in FIG. 14, symbols subjected to the drop display from the top edge 102A of the symbol display frame 102 at the time of starting the unit game may be five symbols aligned in 5 rows by 1 column.
For that purpose, when the unit game is started with the BET number displayed on the BET number display part 101, one symbol is statically displayed in each symbol display area which forms the prescribed area being in contact with the bottom edge 102B of the symbol display frame 102 as indicated in the lower image display panel 6 shown on the right position on the 1st stage in FIG. 14. In this regard, in FIG. 15, each symbol display area in which an elliptical symbol is displayed shows one example of the prescribed area being contact with the bottom edge 102B of the symbol display frame 102.
As indicated in the lower image display panel 6 shown at the right position on the 2nd stage in FIG. 14, the lowermost symbol among five symbols aligned in 5 rows by 1 column is displayed in the rightmost side of the symbol display area being in contact with the upper edge 102A of the symbol display frame 102. Then, the drop display of the five symbols aligned in 5 rows by 1 column is performed by moving the five symbols downward within the symbol display frame 102.
Then, as indicated in the lower image display panel 6 shown at the left position on the 2nd stage in FIG. 14, when each of the symbols subjected to the drop display is displayed as it is landing on the statically displayed symbol, each symbol is statically displayed in the symbol display area subjected to the landing display.
At this time, when the symbols subjected to the fixed display in the symbol display area are of the same display color (attribute) and are in a state of being adjacent to each other in any one of the four directions vertically and horizontally, all the symbols displayed in the symbol display areas are treated as being in a connected state. In this regard, the symbols being in the connected state are connectedly displayed by applying the texture mapping to backgrounds in the symbol display areas in which the symbols are displayed as indicated in the lower image display panel 6 shown at the left position on the 2nd stage in FIG. 14.
When four or more symbols having the same color combination (attribute) are displayed in the corresponding number of symbol display areas neighboring with each other, the outer frame 106 of a group formed by the corresponding number of symbol display areas is highlighted as indicated in the lower image display panel 6 shown from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 14. Then, the elimination display of removing the outer frame 106 and each symbol in the outer frame 106 is performed as indicated in the lower image display panel 6 shown from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 14. At this time, the payout for the elimination display is provided. In this regard, the amount of the provided payout is the amount obtained by multiplying the number of outer frames 106 subjected to the elimination display by the standard amount of payout. More specifically, there is one outer frame 106 subjected to the elimination display in the lower image display panel 6 shown from the left position on the 2nd stage to the left position on the 3rd stage in FIG. 14. Since the standard amount of payout is set to “10” at this moment, a payout amounting to 1×“10”=“10” is provided, and the amount of payout “10” is displayed in the payout number display part 9 as a payout number. In addition, when the payout is provided, the standard amount of payout is doubled.
Subsequently, as indicated in the lower image display panel 6 shown from the left position on the 3rd stage to the right position on the 3rd stage in FIG. 14, if there are symbols statically displayed in symbol display areas located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102, the symbols are subjected to the drop display by moving the symbols downward within the symbol display frame 102.
Subsequently, the game progresses as in the above-mentioned case. That is, when each symbol subjected to the drop display is displayed as they are landing on a statically displayed symbol as indicated in the lower image display panel 6 shown on the right position on the 3rd stage in FIG. 14, each symbol is statically displayed in a symbol display area subjected to the landing display. However, here, even when each symbol subjected to the drop display is displayed as they are landing on the lower edge 102B of the symbol display frame 102, each symbol is statically displayed on the symbol display area subjected to the landing display.
At this time, when the symbols statically displayed in the symbol display areas are of the same display color (attribute) and in a state of neighboring with each other in any one of the four directions vertically and horizontally, all the symbols displayed in the symbol display areas neighboring with each other are treated as being in a connected state. The symbols being in the connected state are connectedly displayed by applying the texture mapping to backgrounds in the symbol display areas in which the symbols are displayed as indicated in the lower image display panel 6 shown at the right position on the 3rd stage in FIG. 14.
When each symbol connectedly displayed is in the state where four or more symbols are adjacent to each other, the outer frame 106 of a group formed by each symbol display area in which each symbol participating in the adjacency is displayed, is highlighted as indicated in the lower image display panel 6 shown at the right position on the 3rd stage in FIG. 14. Then, the elimination display of removing the outer frame 106 and each symbol in the outer frame 106 is performed as indicated in the lower image display panel 6 shown from the right position on the 3rd stage to the right position on the 4th stage in FIG. 14. A payout for the elimination display is provided at this time. In this regard, the amount of the provided payout becomes the amount obtained by multiplying the number of outer frames 106 subjected to the elimination display by the standard amount of payout. More specifically, there are two outer frames 106 subjected to the elimination display in the lower image display panel 6 shown from the right position on the 3rd stage to the right position on the 4th stage in FIG. 14. At this moment, since the standard amount of payout is “20”, a payout amounting to 2×“20”=“40” is provided, and a numeral obtained by adding “40” of the amount of payout to the current payout number is displayed in the payout number display part 9. When this payout is assigned, the standard amount of payout is further doubled.
Also subsequently, if there are symbols statically displayed in symbol display areas located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102, the drop display of the symbols is performed by moving the symbols downward in the symbol display frame 102. Then, the game further progresses as shown in the above-mentioned case.
If there is no symbol statically displayed in the symbol display area located above the symbol display areas subjected to the elimination display of symbols within the symbol display frame 102 as indicated in the lower image display panel 6 shown at the left position on the 4th stage in FIG. 14, the unit game terminates at the time.
The row number of symbols (that is, the number of symbols) subjected to the drop display from the top edge 102A of the symbol display frame 102 at the time of starting the unit game is changed according to the BET number bet on the unit game. In the example shown in FIG. 14, the drop display of six symbols aligned in 5 rows by 1 column is performed from the top edge 102A of the symbol display frame 102 when the BET number is “1”.
That is, when the BET number is “1”, five symbols aligned in 5 rows by 1 column are subjected to the drop display from the upper edge 102A of the symbol display frame 102. FIG. 16 is a diagram showing an aligned state of symbols subjected to the drop display from the top edge 102A of the symbol display frame 102 at the time of the start of the unit game for which the BET number is set to “1.” As shown in FIG. 16, at the time of the start of the unit game for which the BET number is set to “1”, a group 107A of five symbols aligned in 5 rows by 1 column are subjected to the drop display from the top edge 102A of the symbol display frame 102.
When the BET number is “2”, nine symbols aligned in 5 rows by 2 columns are subjected to the drop display from the top edge 102A of the symbol display frame 102. FIG. 17 is a diagram showing an aligned state of symbols subjected to the drop display from the upper edge 102A of the symbol display frame 102 at the time of the start of the unit game for which the BET number is set to “2”. As shown in FIG. 17, at the time of the start of the unit game for which the BET number is set to “2”, a group 107B of nine symbols aligned in 5 rows by 2 columns are subjected to the drop display from the top edge 102A of the symbol display frame 102.
When the BET number is “3”, twelve symbols aligned in 5 rows by 3 columns are subjected to the drop display from the top edge 102A of the symbol display frame 102. FIG. 18 is a diagram showing an aligned state of symbols subjected to the drop display from the upper edge 102A of the symbol display frame 102 at the time of the start of the unit game for which the BET number is set to “3”. As shown in FIG. 18, at the time of the start of the unit game for which the BET number is set to “3”, a group 107C of twelve symbols aligned in 5 rows×3 columns are subjected to the falling display from the top edge 102A of the symbol display frame 102.
Since the configuration and the control of a slot machine in the case shown in FIG. 14 are the same as the configuration and the control of the slot machine 1 in the case shown in FIG. 1, the description is omitted.
The present invention can be applied to a display technique concerning the rearrangement of symbols in the slot machine.
Further, a gaming machine and a game system as described below may be provided in accordance with the present invention.
In a slot machine according to the present embodiment of the present invention, the game controller operates to cause the display to perform a variety of display of one symbol having one of the plurality of attributes in a plurality of symbol display areas arranged in a matrix manner in the display frame. At this moment, the game controller operates to cause the display to display statically a first predetermined number of symbols in a first corresponding number of symbol display areas forming a first predetermined range positioned on a bottom edge of the display frame at a beginning of a unit game. And the game controller operates to cause the display to perform a drop display of a second predetermined number of symbols in a second corresponding number of symbol display areas forming a second predetermined range positioned on a top edge of the display frame wherein the second predetermined number of symbols are moved downward from the top edge through empty symbol display areas positioned below the second predetermined range and above the first predetermined range.
The game controller operates to cause the display to display statically the second predetermined number of symbols in a third corresponding number of symbol display areas forming a third predetermined range after the second predetermined number of symbols are landed on the first predetermined range, which is located just above the third predetermined range. The game controller also operates to cause the display to display all symbols having a same attribute in a fourth corresponding number of symbol display areas, each of which neighbors on at least one of four directions: up and down and left and right, in a grouped manner.
